心肌梗塞病人有室性心律失常者,随访1至4年的死亡率增高。连续动态ECG记录到各种室性心律失常,可作为总死亡和猝死的预测因素。但是,监护多长时间对帮助处理病人比较有用,目前仍不清楚。显然,在尽可能短的时间内,获得有助于处理病人的资料,对方便病人和节约费用都是有益的。作者的目的是检验不同的动态ECG记录时间对分析梗塞后病人死亡危险的价值。方法:3837例梗塞后病人参加有安慰剂对照的β阻滞剂(普蔡洛尔)心脏病发作随机临床试验(BHAT),3290例在梗塞后2～21天做了24小时动态心电图记录,1336例服安慰剂病人的动态心电图
Ventricular arrhythmias in patients with myocardial infarction were followed up for 1 to 4 years of increased mortality. Continuous dynamic ECG recorded a variety of ventricular arrhythmias can be used as predictors of total death and sudden death. However, it remains unclear how long the custody will be useful to help patients. Obviously, in the shortest time possible, getting information that helps with patient care is good for patient convenience and for cost savings. The aim of the authors was to examine the value of different dynamic ECG recording times in analyzing the risk of death after a patient’s infarction. Methods: A total of 3837 post-infarction patients participated in a placebo-controlled randomized clinical trial of beta blockers (propranolol) in a heart attack (BHAT) and 3290 patients underwent 24-hour Holter recordings 2 to 21 days after infarction, 1336 patients taking placebo ambulatory electrocardiogram
